Later, Feng Ang, the general of Gaozhou, led troops to attack Luodou Cave and put down the rebellion. In the eighth year of Zhenguan in Tang Dynasty (AD 634), Nanfuzhou was changed to "Douzhou" because of Luodou Cave and Jiangdou River, which was one of the seventeen states under the jurisdiction of Cennan in Tang Dynasty. It took 437 years from 634 to 107 1.
